Abstract：

Plastic deformation of the extrusion punch and surface folding on part often occur during the forming of outer race (VL.). The occurrence causes of the problems are studied by using FE method. The coupled thermal\|mechanical elastic\|plastic FEM analysis models for multi\|stage warm extrusion are set up, and each forming process is simulated by using non\|linear FEM software MARC. According the simulating results, an improving solution is put forward.
